Description

{Multi-purpose strap and method}

The present invention relates to a multipurpose composite cord and a manufacturing method thereof. More specifically, it can be used for various purposes such as shoelaces, belts, ribbons, sandal bands, bracelets and the like depending on the user's preference. In addition, it can be used for various purposes such as improving the aesthetics and having high tensile strength, elasticity, The present invention relates to a composite cord and a manufacturing method thereof.

In general, many items used in real life such as shoes, clothing, ornaments are made of various materials. For example, natural materials such as natural fibers and leather, artificial materials such as synthetic fibers and synthetic resins, Widely used. In addition, these materials are changed into various types of structures to manufacture articles, one of which is a string.

Such a string may have various uses in itself, or may be formed by twisting two or more strands together to form a variety of structural strings having different shapes and shapes, or by making the strings into various shapes with other linear materials to form a band , Or they may be woven in the form of woven fabrics.

Such variously modified straps can be used, for example, for sandals or bands of sandals, and can be made of a number of fine fibers, such as natural fibers such as cotton, hemp, wool, etc., or synthetic fibers such as polyester, nylon, However, they have various problems such as the shape of the band, the shape of the band, the shape of the woven fabric, etc., and the shape stability (including the dimensional stability and the like) and the aesthetics are decreased and easily increased.

In addition, although a leather strap has been preferred as a material capable of exhibiting shape stability and aesthetics, it is expensive and difficult to exhibit various colors, and is difficult to be easily treated, such as being easily contaminated.

In recent years, a composite cord capable of exhibiting the advantages of a leather strap at an inexpensive value has been developed and partially used. This is a synthetic resin sheet having a high tensile strength (very low elasticity) coated with a narrow synthetic resin sheet , It can be manufactured in various forms because of its excellent shape and color feel, but it can not have the same texture as leather strap (moderate volume and cushioning property). Therefore, the article manufactured using such a composite strap is rigid, There is a problem that the contact property with the skin and the skin affinity are poor.

In addition, the twisted rope made of twine or more twine is difficult to produce a smooth aesthetic appearance because the bent surface of the knot does not form a smooth curved surface due to rigidity of the material.

In addition, the multi-purpose synthetic leather composite cord according to the prior art is formed of a linear core material having a low elongation and a high toughness, and a long strip-shaped synthetic leather material (for example, In the case of a synthetic leather having a low flexibility such as natural leather, both ends of the contour are smoothly folded, but the ends of the contour of the contour are smoothly folded. If friction is continued due to frequent movements when used on a shoelace, there is a problem that the outer surface of the string is loosened or peeled and the damage is accelerated, and foreign substances such as dust,

In addition, it is possible to improve the affinity of the skin to suppress the skin allergy of the user.

The outer covering 100 is not limited to leather and leather but is made of either a rubber material having a predetermined elasticity or a PU (polyurethane) material, so that the outer covering 100 can be used as a substitute for a band or belt So that the availability according to the use purpose can be expanded.

In addition, since the outer covering 100 is further formed with the guide grooves 104 formed concavely and concavely in line with the reference line 102 on the upper surface thereof, the outer covering 100 is made of natural leather, synthetic leather, Both ends of the outer covering 100, that is, the lamination portion 120, can be smoothly folded on the basis of the guide groove 104 even if the outer covering 100 is made of synthetic rubber.

The inner member 200 is adhered to the upper surface of the outer member 100 such that both ends of the inner member 200 are covered with the lamination portion 120 of the outer member 100 to further increase the elasticity and tensile strength of the outer member 100 And the decorative core material 300 are firmly adhered to each other.

The inner member 200 is made of the same material as or different from the material of the outer member 100 and is recessed on the upper surface of the inner member 200 to form a seating groove 220 on which the decorative core member 300 is seated.

The seating groove 220 is formed in a hemispherical shape and is preferably formed in a shape corresponding to a lower end surface of the decorative core member 300 to which the decorative core member 300 is coupled so that the decorative core member 300 is stitched Can be combined.

The inner member 200 is formed in the shape of a plate and has a base line 102 formed on its upper surface and both ends of the inner member 200 are folded upward against the reference line 102 to be adhered to the upper side. And both ends of the outer member 100 are seated and coupled to the upper surface of the outer member 100 so as to be wrapped by the lamination unit 120 of the outer member 100 by using a heat pressing method to maximize the elasticity and tensile strength of the outer member 100 have.

The decorative core material 300 is formed in a bar shape and is a component for improving the aesthetics while improving the tensile strength, elasticity and toughness of the multi-functional composite cord of the present invention.

The decorative core member 300 has a circular or polygonal cross section and is preferably made of a color different from that of the outer member 100 and has an outer surface formed in a spiral shape or a surface of the decorative core member 300 having dimpled or irregular lines Or a plurality of microprojections are formed, whereby the aesthetics can be improved.

Since at least one or more of the decorative core members 300 are disposed in close contact with each other horizontally on the upper surface of the inner member 200, the tensile strength elasticity and the aesthetics of the versatile composite cord of the present invention can be further improved, Is preferably made of a synthetic leather material in which a base of a nonwoven fabric or a fabric is coated with PVC or the like, but is not limited thereto, and may be made of a rubber material PU (polyurethane) material having predetermined elasticity or fiber yarn, , Or a natural leather material.

The decorative core member 300 is firmly coupled to the upper surface of the inner support member 200 by a transparent sheet meal 240. The transparent core member 240 is preferably bonded to the decorative core member 300 using an air- The inner surface of the inner member 200 is fixedly coupled to the upper surface of the inner member 200 in a stitched manner along the length of the inner member 200,

Hereinafter, a method for manufacturing a versatile composite cord according to a preferred embodiment of the present invention will be described.

The method for manufacturing a versatile composite cord according to a preferred embodiment of the present invention includes a bonding step S100 of firstly folding and bonding the laminated portion 104 of the outer support 100 along the reference line 102 to the upper surface of the outer support 100 A step S120 for joining the decorative core member 300 to the upper surface of the inner member 200 to join the decorative core member 300 using a sheet meal 240, (S140) for placing the inner member 200 coupled with the decorative core member 300 on the upper surface of the outer member 100, applying an adhesive to the upper surface of the lamination portion 104 of the outer member 100 The upper surface of the laminated portion 120 of the outer covering 100 is placed on the upper surface of the outer covering 100 so as to surround both ends of the inner covering 200, And a cover step (S160) in which both ends of the main body (100) are coupled while being folded secondarily.
